Clutch is starting to slip around 4K RPM on E43 fuel (7g E85 + 9g 91oct) on 2nd, 3rd or 4th gear. It drives fine normally but not on WOT.
Options:
ACT - nice price but low engagement point
HPF - expensive but smooth and stock engagement point, can also weld
South Bend - I emailed the guy and the organic one is rated for 500 ft/lbs of torque. Has anyone actually installed this? How is the engagement point?
